SHEET-FILING.

To all whom it may concern:

Be it known that I, WILLIAM L. GIBB, a citizen of the United States, residing at Ocean City, in the county of Cape May and State of New Jersey, have invented certain new and useful Im rovements in Sheet-Piling, of which the fo lowing is a specification.

My invention relates to improvements in sheet piling, the object of the invention being to provide an improved construction of sheet ile composed of sheet metal plates riveted3 together and constituting a hollow water passage from its upper to its lower end, the lower end of the pile being open to permit the escape of the water to displace the sand and allow the pile to sink.

A further object is to provide improvements of this character with tongue and groove formation ermitting the piles to be assembled in a tig t wall.

With these and other objects in view the invention consists in certain novel features of construction, and combinations and arrangements of parts as will be more fully hereinafter described and pointed out in the claims.

In the accompanying drawings, Figure 1, is a view in side elevation illustrating my improvements. Fig. 2, is a view in longitudinal cross section, and Fig. 3, is a view in horizontal cross section.

My improved pile, comprises in the main two plates 1, 1, of sheet metal bent as shown in Fig. 3, and secured together by rivets 2. It will be seen that throughout the greater portion of the width of the pile the sheets 1, l, are spaced apart forming a hollow chamber, the sides of which latter being tightly closed when the edges of the plates 1, 1, are bent inwardly and securely riveted. The edges of the plates 1, 1, at one edge of the pile are flared a art as shown at 3 forme ing a groove, and tile edges of the sheets at the opposite edge of the pile are disposed flatly against each other forming a tongue 4 to enter the groove of an adjacent pile to form a continuous wall.

The upper end of the pile is closed by a cap plate 5, of a shape to exactly fit the h oln low pile, and provided with depending flanges 6, and rivets 7 are projected through the sides 1, 1, and through said fianges 6 to secure the cap in place.

An inlet opening 7 is provided in one side plate 1 near the upper end of the pile and is Specification of Letters Patent.

preferably strengthened by an internally screw threaded boss 8 to receive the pipe not shown, to connect the pile with the source of hydraulic pressure.

An angle bar 9 is secured to one side face of the pile near its lower end and serves by its cam action against the ground to guide a newly inserted pile into close engagement with the pile previously driven.

A hook 10 is secured to one side of the pile near its upper end to facilitate withdrawing the pile from the ground and to support the pile in position when it begins to enter the ground.

The lower end of the pile is open and in operation after the pile is inserted in position, water under hydraulic pressure is admitted through inlet 7, and iiows down through the pile, escaping at the lower end, displacing the sand and dirt and allowing the pile to settle.

Various slight changes might be made in the general form and arrangement of parts described without departing from my invention, and hence I do not restrict myself to the precise details set forth, but consider myself at liberty to make such changes and alterations as fairly fall within the spirit and scope of my invention.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is:

1. A pile adapted to be hydraulically driven, comprising two plates of sheet metal secured together throughout their longitudinal edges, the plates at one edge of the pile flared apart forming a groove, the plates at the other edge of the pile forming a tongue, a cap plate closing the upper end of the pile, flanges on said cap plate secured to the side plates means for admitting water to the pile, and the lower end of the pile open, substantially throughout the width thereof, whereby the water may freely escape under the edges of the pile.

2. A pile adapted to be hydraulically driven, comprising two plates of sheet metal secured together throughout their longitudinal edges, the plates at one edge of the pile flared apart forming a grooye, and the plates at the other edge of the pile disposed flatly together forming a tongue, a cap plate, deending flanges on the cap plate projecting etween the pile plates and conforming in shape to the interior of the pile, rivets passing In testimony Whereot1 I have signed my name to this speeiieation in the presence of tWo subscribing witnesses.
